Nano science and nanotechnology are new frontiers of this century and food nanotechnology is an emerging technology. Food nanotechnology is an area of emerging interest and opens up a whole universe of new possibilities for the food industry. In food engineering, two major applications related to nanotechnology (i.e)…
Emerging infectious diseases and the increase in incidence of drug resistance among pathogenic bacteria have made the search for new antimicrobials inevitable. In the current situation, one of the promising and novel therapeutic agents could be the nanoparticles. In this study, antimicrobial susceptibility testing of…
The solid state reactions of BaTiO3 formation from a mechanically activated BaCO3-TiO2 powder mixture have been investigated. Thermogravimetric TGA, thermomechanical TMA, scanning electron microscopy SEM, X-ray diffraction XRD and reactions thermodynamic analyses have been used in the present study. The results of the…

A supramolecular polymer gel was prepared from self-assembly of a heteroditopic A–B monomer based on benzo[18]crown-6. Such a gel shows interesting gel–sol transitions in response to dual-stimuli owing to the dynamically reversible complexation between benzo[18]crown-6 and primary alkylammonium salt moieties.
By means of limiting oxygen index (LOI), cone calorimeter, and TG-DSC tests, this paper investigated the effect of unmodified montmorillonite (MMT), organically modified montmorillonite (OMMT), and aluminium trihydrate (ATH) additions on the flame retardancy for asphalt combustion. Experimental results showed that add…
We report the properties of glycoconjugated porphyrin dimers behaving as highly sensitive ratiometric temperature sensors in water. This effect results from interactions between carbohydrate and water altering molecular relaxation kinetics leading to temperature sensitive dual emission. These dimers are robust ratiome…
We applied AIEE to the visualization of crystal formation processes. We found that J-aggregates act as precursors for crystal nuclei, and that the growth from J-aggregates to crystal nuclei is the rate-determining step in the nucleation process.
A new method for facile fabrication of high refractive index materials that is based on simple blending of polymers and heteropoly acids is demonstrated. This hybridization is shown to dramatically increase the refractive index of the general polymer, while maintaining a high transparency.
Using transformation electromagnetics concept, we introduce an approach to virtually delocalize radiating sources and to transform their radiation pattern at the same time. We propose the design of an electromagnetic device that can virtually change the location of the emission point. By applying radial transformation…
Mullite fibres/whiskers frameworks (MF/MW frameworks) were prepared by mixed-slurry-filtration and heat-treating. Hierarchical fibres/whiskers structure formed in the frameworks through fluorine-catalyzed gas-phase reaction. Topaz rods as a transient product first formed in the frameworks, and then gradually transform…
The synthesis and gelation properties of a structurally simple, renewable-resource-based glucose-triazole-hydrogenated cardanol conjugate (GTHCC) are reported. The conjugation of hydrogenated cardanol and glucose was done using a triazole linker employing copper(I) mediated acetylene azide cycloaddition ‘click’ chemis…
The facile and efficient InCl <sub>3</sub> /2-iodophenol-catalyzed polycyclotrimerization of diynes to generate regioregular hyperbranched polyarylenes was successfully established.
Novel hybrid nanocomposites of Cu2O nanoparticles (NPs) partially embedded in CuO nanowires (NWs) were produced by simple thermal reduction of CuO NWs in a vacuum. It is found that most Cu2O NPs adopt two regular shapes, one being cubic and the other being octahedral. The shape selection of the Cu2O nanocrystals is go…
Jatropha Curcas leaf was investigated as a green inhibitor on the degradation of mild steel in 4 M HCl and 4 M H 2 SO 4 aqueous solutions using gasometric technique. Mild steel coupons of dimension 2 1.5 cm were immersed in test solutions of uninhibited acid and also those with extract concentrations of 4 ml, 6 ml, 8…
Four different graphene films were synthesized via chemical vapor deposition by using acetonitrile with feed rates of 0.01, 0.02, 0.04, and 0.06 mL/min. Heterojunction solar cells were assembled by transferring as‐synthesized graphene films onto n ‐Si. Solar cells based on graphene samples produced at 0.01, 0.02, 0.04…
A very high purity (99.99+%) high temperature co-fired ceramic (HTCC) alumina has recently become commercially available. The raw material of this HTCC alumina is very different from conventional HTCC alumina, and more importantly there is no glass additive in this alumina material for co-firing processing. Previously…
Carbon nanotubes (CNTs) continue to attract significant interests due to their unique combination of extraordinary thermal, electrical, optical, and mechanical properties. The preparation of CNTs coated with magnetically sensitive Fe 2 O 3 nanoparticles has implications to the development of advanced heat transfer nan…
The mesomorphism of bent-rod dimers with a very long flexible linker strongly depends on the structure of the spacer and the rod-core.
A new optical encoding approach, the wavenumber–intensity joint surface enhanced Raman scattering (SERS) spectral encoding method, was demonstrated by using silver nanoparticles with a core–shell structure.
